Mount the Mint Mate VM as a secondary disk on some convenient VM and 
edit the password file to blank the password then dismount it and 
attempt to restart it again.  You might also edit ssh config to turn on 
ssh so you can ssh into it once it's started.  Or edit the X configs to 
get rid of X and boot to a command line login (I assume it's booting to 
X login)
